A little update here: My in laws requested a mirror so I went to Ikea to get another one. They have it there still, but no they ARE 47 1/4” long instead of the 47 3/4” I had. Apparently I got one of the last of an old stock that was 1/2” longer. As such, I’ve updated my Sketchup models and material lists to reflect the correct size. If you downloaded them before you may want to get the updated versions.
